Disclaimer: I like Railway.
Heroku VMs had the kitchen sink, and I miss that with Railway. A pretty standard Phoenix app with Phoenix’s built-in auth doesn’t build and the user is presented with build errors about nixpacks. Now there’s a good deal I have to learn just to get bcrypt to build.
You might be interested in Railway's CLI deployments: `railway up` from your project root gets ya going.
